Registering Your Arrival in Luxembourg: Deadlines and Documents

Register your arrival with the population office of the Luxembourg commune where you actually live. A person moving from abroad normally declares the new usual residence within eight days. A third-country national who is not the family member of an EU citizen should act within three days: Guichet gives a three-day deadline, while Luxembourg City describes three working days for its local procedure. Contact the commune before travelling to the counter, because it may request documents beyond the national baseline.

Where and when do newcomers register?

The declaration is made to the bureau de la population of the communal administration responsible for the new address. It is an address-registration step: the commune records the resident in the communal register and the National Registry of Natural Persons, or RNPP. It is not an immigration authorisation and does not replace a visa, temporary authorisation to stay, EU registration certificate or residence permit.

• EU, EEA and Swiss citizens: if staying longer than three months, declare arrival at the commune within eight days and complete the relevant registration certificate within 90 days.
• Third-country nationals who are not EU-family members: declare arrival within three days. Do not wait for the end of the general eight-day period.
• Third-country family members of EU citizens: the residence route differs; declare the address and ask the commune which EU-family-member form and evidence apply.
• People moving inside Luxembourg: declare the new address within eight days of occupying it. When moving to a different commune, the new commune removes the resident from the old register.

The initial arrival from abroad is normally handled with the commune directly. MyGuichet offers an authenticated procedure for a change of usual residence, including moves within Luxembourg, but the national guide tells newcomers from abroad to present themselves at the commune. Check the chosen commune's appointment rules, opening hours and accepted filing methods rather than assuming the capital's process applies everywhere.

Which documents are needed for the arrival declaration?

Everyone should bring a valid national identity card or passport. A first registration generally also requires family-status evidence where relevant: a family record book, marriage or registered-partnership certificate and children's birth certificates. The commune can ask for more, so obtain its checklist before the deadline.

Luxembourg City's published checklist illustrates the address evidence a commune may accept. It lists a lease, a recent electricity or water bill, a recent landline bill, another document issued by a public administration, or an accommodation certificate signed by the owner or tenant when the newcomer cannot produce one of those records. This is a useful preparation list, but another commune can set its own documentary details.

• A valid identity card or passport for each person being registered;
• the lease, deed, utility evidence or accommodation certificate requested by the commune;
• marriage, partnership, birth or divorce records needed to establish family status;
• for a third-country national, the original temporary authorisation to stay, any required visa and the relevant passport or existing residence document;
• an official translation by a sworn translator for documents not drawn up in German, French or English.

Bring originals where the commune requests them and keep digital and paper copies. A spelling difference between a passport, birth certificate and lease can delay the RNPP record, so verify names, dates and the full address before the appointment.

What must EU and third-country residents do next?

For an EU, EEA or Swiss citizen staying longer than 90 days, the arrival declaration is followed by a registration certificate at the commune within three months. The supporting evidence depends on status. A salaried worker supplies a compliant employment contract or commitment to hire. A self-employed person uses the relevant business or professional authorisation. A student provides enrolment, sufficient resources and health cover; a non-working resident provides sufficient resources and comprehensive health insurance. EU family members provide the relationship documents required for their category.

A third-country national staying longer than 90 days follows the route authorised before arrival. At the commune, the person presents the original temporary authorisation to stay, a valid passport and any visa required. The application for the residence permit matching the authorised category—such as employee, self-employed person or student—must then be filed within 90 days of arrival. The commune declaration and the residence-permit process are connected steps, not substitutes for one another.

What changes after the address is registered?

Once registered in the RNPP, a resident can obtain a residence certificate. It records the legal address; an extended certificate can list a spouse, registered partner and children who share the usual residence. Generating either document in a private MyGuichet space is free, while a commune may charge a chancery fee. Authorities commonly ask for a certificate issued within the previous three months.

Government administrations are generally informed of address changes through the RNPP, but Guichet still recommends notifying organisations with which the resident regularly deals. Give a new tax card to the employer when the tax administration issues one. A person with a Luxembourg-registered vehicle must update the address on the registration certificate with the SNCA within one month. Banks, insurers, schools, healthcare providers and utility companies also need the usable address even when they are not part of the automatic state exchange.
